Happy Birthday, my beautiful brilliant boy. My world is so much bigger, so much happier since you were born. Many, many happy returns of the day to you -- may all your wishes come true.
(Except the wish for your own X-ray machine. Or the one about having a Pterodactyl for a pet. And ix-nay on the time machine, too. Yeah, Mom's no fun. Good thing you're fun enough for us both!)
